    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 %>}6>nT#  
    f m.-*`ax  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: w}^z1n  
    enableservice('AutomationServer', true) a(s}Ec${Z  
    enableservice('AutomationServer') &bBK#d*-u?  
    B\A2Vm`&  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Udv5Y

    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: !r$?66q/  
    1. 在FRED脚本编辑界面找到参考. qlmz@kTb  
    2. 找到Matlab Automation Server Type Library Fyoy)y*  
    3. 将名字改为MLAPP 6T0E'kv S

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 lG,/tMy

    1. 创建Matlab服务器。 (nfra,'  
    2. 移动探测面对于前一聚焦面的位置。 2KMLpO&De

    4. 在探测面计算照度 O= PFr"  
    5. 使用PutWorkspaceData发送照度数据到Matlab <n< @ O5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 J Sz'oA5  
    7. 用Matlab画出照度数据 f~-81ctu
